Pt-Ni nanoparticles supported on carbon-ceramic electrode (Pt-Ni/CCE) are prepared by an electrodeposited process. The catalysts are characterized by Scanning electron microscopy, Energy-dispersive X-ray spectroscopy (EDX) and cyclic voltammetry. The results show that the Pt-Ni nanoparticles dispersed uniformly on carbon-ceramic electrode. The Pt-Ni/CCE catalysts have higher electrocatalytic activity for formic acid oxidation than a comparative Pt/CCE and show great potential as less expensive electrocatalyst. The effect of some experimental factors was studied and optimum conditions were suggested. Finally, the long-term stability of the modified electrode has also been investigated. These results indicate that the system studied in the present work is the most promising system for use in Direct Formic Acid Fuel Cells (DFAFCs).
